摘　　要：目的应用经食管实时三维超声定量分析二尖瓣成形术前后瓣环三维立体结构的变化。方法入选二尖瓣脱垂并单纯施行二尖瓣成形术的患者38例为病例组,对照组20例。应用经食管实时三维超声观察并使用Qlab软件分析瓣环结构。结果病例组术前瓣环前后径、横径、2D投影面积、3D面积较对照组增大(P均<0.05),椭圆度减小(P<0.05),高度、3D面积与2D投影面积之比及高度与横径之比无明显差异(P均>0.05)。病例组术后瓣环椭圆度较术前明显增大(P<0.05),与对照组相近,其余各指标均显著减小(P均<0.05)。结论二尖瓣脱垂患者瓣环扩张、形态趋于圆形;成形术后瓣环明显缩小、椭圆形态恢复、马鞍形态扁平化,近期效果良好,远期意义值得随访观察。Objective To analyze the 3D structure of mitral annulus in patients with mitral valve （MV） prolapse before and after MV repair with real-time 3D transesophageal echocardiography （RT-3D TEE）. Methods RT-3D TEE was performed in 38 patients and 20 controls. Qlab was used for 3D quantification analysis. Results MV prolas- ed patients had larger APD, CW, 2D A, 3D Min A （P〈0.05）, smaller ellipticity（P〈0.05）, while H, 3D Min/2D A, AHCWR were similar （P〈0.05）. After MV repair, ellipticity became larger and similar to the controls. All the other parameters significantly decreased （P%0.05）. Conclusions MV prolapsed patients had enlarged and more cir- cular annulus. After MV repair, the annulus decreased obviously in dimensions and become more flattened while re- gained annular ellipticity.
